<h3>Ellipsoid Correction RD Operator</h3>

<p>
    The operator implements the&nbsp;Range Doppler
    orthorectification method [1].
    The implementation is exactly the same as for the&nbsp;<a href="RangeDopplerGeocodingOp.html">Range Doppler Terrain
    Correction operator</a>
    except that the averaged scene height is used instead of DEM.</p><h4>Parameters Used</h4>

<p>
    The following parameters are used by the operator:
</p>
<ol>
    <li>Source Band: All bands (real or virtual) of the source
        product. User can select
        one or more bands. For complex product, i and q bands must be selected
        together. If
        no bands are selected, then by default all bands are selected.
    </li>
    <li>Image resampling method: Interpolation methods for
        obtaining pixel values from
        source image.&nbsp;
    </li>
    <li>Map Projection: The map projection types. The orthorectified image will&nbsp;be presented with the user selected
        map projection.
    </li>
</ol>
